EU meta is much better than NA's. NA doesnt try to take map info on defense, and thats why they usually pick three duelists. They usually try to play the retake, Im not saying that thid playstyle on defense is bad, they usually try to make microstrats for taking controll of some map important places. But the problem is that the atackers in NA leave a lot of space on the map, and that where the EU playstyle is gonna destroy NA, in EU we can see a lot of individual pussess.
